TIE-PLATE.

Specification of Letters Patent.

Patented June 27, 1916.

AppIication filed April 18,1916. Serial No. 92,015.

I do hereby declare the following to be a" full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains. tov make and use the same.

The primary object of this invention is to admit of the fastening spikes employed for holding a tie plate on a wooden tie being securely held in operative position and prevented from working loose.

Another object of the invention is the provision of a tie plate having means associated therewith for penetrating the tie, said means being adapted to compress the fibers of the i Re a the point of insertion of the spike, so

.as to increase '2 fr ctional engagement between the spike and the tie.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawing forming a part thereof, in which:

Figure l is a,bottom plan View of the plate removed from the tie, Fig. 2 is a side view thereof, Fig. 3 is a transverse section taken through one end of the plate, and showing the fiber compressing means in' operative position in the tie.

Referring to the drawing in detail, the numeral 1 designates a rectangular shaped tie plate adapted to be mounted on the upper side of a tie, at one end thereof, as shown in Fig. 3 of theldrawing. The upper side of the plate 1 is provided with a transverse bib 3. designed to engage the adjacent longinudinal edge of the base flange of the rail, not shown. end, with a pair of spike-receiving openings and is provided adjacent its opposite ends with another spike-receiving opening 5, the latter opening extending through the plate and the rib Depending from the under s-ide,of the plat e l are pairs of fiber compressing-members 6 and 7. The fiber com- .pressingniembers forming the pair 6 are of {'engthsiconsiderably greater than the length n the members forming the pair 7 and are The plate is provided, at one located on opposite sides of the opening 5,

and In spaced relation thereto, and as shown" in Fig. 1 of the drawing, the said members have their inner ends converging and terminally spaced fro'm each other. The other 133.12 of fiber compressing members are located between the openings 4 and are arranged .in' converging relation and have their inner ends spaced from each other. The members forming the pairs 6 and 7 have their lower edges sharpened, as shown at 8, and the members forming the pair 6 have their opposed inner faces beveled, as

shown at 9, and have their outer faces 7 straight, as shown at 10, and ethe members forming the pair 7 have their outer surfaces beveled, as shown at 11, and their inner surfaces 0r faces straight, as shown at 12. The

compressing members forming the pairs 6 and 7 are mounted on the plate in such relation to the openings 4 and 5, that when the members penetrate the tie the fibers displaced by the beveled faces will be crowded beneath the openings 4: and'5, so that the spikes, designated 13, when driven into the tie will meet with considerable resistance, and the frictional engagement between the spikes and the tie will be increased so as to maximize the anchorage of the spikes.

Having thus described my invention what I claim as new is:

1. The combination with a wooden tie, of a. plate mounted on the upper side of the tie and provided with spike-receiving openings, and spaced pairs of converging tie penetrating and fiber compressing members carried by the under side of the plate and located adjacent the openings.

2. The combination with a wooden tie, of a plate mounted on the upper side of the tie and provided with spike-receiving openings, spaced pairs of tie-penetrating and fiber compressing members carried by the under side of the plate and located between the openings, the penetrating members forming one pair being of a greater length than the members forming the other pair.

In testimony whereof I affix my signature in presence of two witnesses.
